Wedderburn, OR Coastal Erosion Rate
Shoreline change 0.9 miles north of Wedderburn, OR
Good news, and an honest one: USGS's data can't distinguish this stretch, 0.9 miles north of Wedderburn, OR, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
The grain of this number
USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Wedderburn, OR, rather than showing one arbitrary line. Segment center: 42.45, -124.42. The survey behind it runs to 2002-2011, in USGS's Pacific Northwest assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
How solid is this number
This reading comes from 33 individual transects averaged together, 18% of which measured erosion rather than growth. USGS's confidence interval here is ±2.35 ft/yr. The unadjusted figure here, 0.33 ft/yr, would place it 973 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2012-1008. Coronado, CA sits at national rank 1147 for growth (1.69 ft/yr), one reference point among the 1211 scored segments, 782 miles from here. 0.7 miles up the coast, Wedderburn, OR shows the same lack of a significant trend.
